Question 25895
I belive this is how to solve your equation.
11x(x+3)=0
then you have to make each term equal to zero:
11x=0  x+3=0

for 11x=0 you divide by 11 on both sides which equals 0. x=0
then for x+3=0 you subtract 3 from both sides to get x by itself.
x= -3

Then you want to check the answers in the original problem to see if they are right!
Hope this helps!
